Auto-Empty System
Shark Clean & Empty automatically deposits dirt into a completely sealed base unit that holds dirt and debris for up to 30 days. No more manual emptying after every clean – simply return the vacuum to the dock and let the hands-free Auto-Empty System empty the cordless vacuum's dust-cup into a large bagless base.
Anti-Allergen Sealing
Inside the base, fine dust particles are sealed away after every clean. Anti-Allergen Complete Seal captures and traps up to 99.9%* of dust, allergens and irritants inside the base*, keeping them out of the air you breathe. This is perfect for homes with pets or allergies.
Lightweight Design
This agile cordless stick vacuum is 30% lighter**, so you can enjoy powerful cleaning throughout your home.
Powerful Suction
HyperVelocity accelerated suction power delivers powerful cleaning on all floor types.
Battery and Charging
Charging while stored on the dock, your cordless vacuum is always charged, always empty, and always ready for the next clean. Enjoy up to 40 mins of run-time*** per charge.
Automatic Floor Adjustment
Perfect for all floor types, the brush-roll automatically optimises speed for deep carpet cleaning, and gives you continuous cleaning contact on hard floors. Anti Hair Wrap Technology actively removes hair from the self-cleaning brush-roll as you vacuum, helping to keep it free of tangles.
Handheld Versatility
Instantly detach the handheld vacuum to easily clean using the included Crevice and Pet Tools. Easily remove dust, dirt and pet hair from sofas, furniture, the car and more, and extend your reach up high with the wand.
Additional Features
Quiet Mode provides the option to dock and charge silently, and leave the emptying for later. Powerful LED lights on the floorhead illuminate hidden debris around your home. Easily view remaining battery life and cleaning mode on the LED display.
